Product details

Motor-protective circuit breaker for 0.63 A loads

The Siemens 3RV1021-0GA10-0FJ0 is a SIRIUS motor-protective circuit breaker designed for motor protection, rated at 0.63 A continuous current with a breaking capacity of 100 kA across the full AC voltage range from 240 V to 690 V. The auxiliary switch is present, giving a remote status contact for the PLC or HMI without an add-on block.

Terminals accept solid or stranded conductors: 2× (1 … 2.5 mm²) and 2× (2.5 … 6 mm²) per clamp, or AWG 14–10 for the main circuit. Shock resistance is 25 g for 11 ms, so it holds up in moderate vibration environments.

Frequently asked questions

What is the breaking capacity of 3RV1021-0GA10-0FJ0 at 400 V AC?

100 kA at 400 V AC, and the same 100 kA rating holds at 240 V, 500 V, and 690 V AC.

Where can I buy 3RV1021-0GA10-0FJ0 and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at the time of quote — no stock figures or price are published here.

What is the trip class of 3RV1021-0GA10-0FJ0?

Trip class 10, meaning it will trip within 10 seconds at 7.2× the rated current. This suits standard induction motor starting.
